Bootstrapping six-gluon scattering in planar N=4 super-Yang-Mills theory
Research output: Chapter in Book/Report/Conference proceeding › Article in proceedings › Research › peer-review
We describe the hexagon function bootstrap for solving for six-gluon
scattering amplitudes in the large $N_c$ limit of ${\cal N}=4$
super-Yang-Mills theory. In this method, an ansatz for the finite part
of these amplitudes is constrained at the level of amplitudes, not
integrands, using boundary information. In the near-collinear limit, the
dual picture of the amplitudes as Wilson loops leads to an operator
product expansion which has been solved using integrability by Basso,
Sever and Vieira. Factorization of the amplitudes in the multi-Regge
limit provides additional boundary data. This bootstrap has been applied
successfully through four loops for the maximally helicity violating
(MHV) configuration of gluon helicities, and through three loops for the
non-MHV case.
